Interpretation:
Three technological products are to be named that has improved the world and lives.
Concept introduction:
Technology has changed or revolutionized the daily lives and the world over the years. Technology has built amazing resources and tools by putting helpful information at fingertips. Technology has open the way for multi-operative devices like smartphones and smartwatches. With various revolutions, or changes, technology has also caused our lives faster, better, and easier, and more fun.
Answer to Problem 20SSC
Vaccinations, computers, and electronic funds transfer are the 3 technological products that have improved the world and lives.
Explanation of Solution
Vaccinations: Vaccination is the most useful and effective medical interference ever introduced. It has abolished a huge part of the contagious diseases. Just because of vaccines, approximately 2.5 million lives are rescued every year from contagious diseases like measles, diphtheria, whooping cough (pertussis), tetanus, etc.
Computers: Computers are used in huge numbers all around the world. It helps to resolve global challenges. Computer science is already broadly used in education. It changes the way of work. Computer is used in wide and variety of sectors (like IT, etc). Computer is also use to play games, trade messages with friends, keep diaries, communicate, etc.
Electronic Funds Transfer: It has made the journey more convenient for the people. The people take cash from their bank account any place in the world. The people use PayPal, Google Pay, PhonePe, etc. to buy and sell material. The people can also transfer money from one account to another with the help of electronic funds transfer.
The three technological products that have improved the world and livesare vaccinations, computers, and electronic funds transfer. These technologies made lives faster, better, and easier, and more fun.

This quiz is open textbook / open notes - but you must work alone. You cannot use the internet or the solutions manual for the book. Scan in your work and record an explanation of your mechanism. You may record this any way that you like. One way would be to start an individual Zoom meeting, start recording, "share your screen" and then talk through the problem. This will be converted to an .mp4 file that you can upload into Canvas using the "record/upload media" feature. Pyridine, benzoic acid and benzene are dissolved in ethyl acetate. Design and provide a plan / flow chart for separating and isolating each of these components. Pyridine and benzene are liquids at room temperature. Benzoic acid is a solid. You have ethyl acetate, 2M NaOH, 2M HCI and anhydrous MgSO4 available, as well as all the glassware and equipment that you used in the organic lab this year.
